• 2.3.4 WP01O <br />WP010 is comprised of 5.7 aces of moderate m steeply sloping revegetation that has a <br />predominately westerly aspect. This unit was seeded in 2001 and therefore, has undergone two growing <br />seasons prior to sampling in 2003. A total of 28 plant taxa were observed in the unit (see Table 19). <br />Ground cover (Fgure 12) consisted of 58.1% live vegetation, 3.2% rock, 0.7% standing dead, <br />10.5% litter, and bare soil exposure of 27.4%. Perennial cover across the unit averaged 10.9% with <br />annual and biennial cover averaging 47.2%. The dominant taxa were field pennycress, Russian thistle, <br />and mountain brome (i3romus ma/yinatus) with 31.4%, 13.9%, and 3.2% average cover, respectively. <br />Woody plant density was determined from 15 belt transects and totaled 140 young and mature stems per <br />acre (Table 2) with fourwing saltbush the dominant woody pWnt. <br />Noxious weeds appear to be well controlled in this unit and the annual brome populations are <br />subdued unit-wide. Although wver by the early-seral species, field pennycress and Russian thistle, is <br />elevated, ground cover by perennials appears sufficient to progress to dominance over the next few <br />years. The shrub population is modest, but growing well, espeaally four-wing saltbush. Overall, the unit <br />• appears typical of reasonable two-year old revegetation, therefore no recommendations are proffered <br />other than continued monitoring, especially during the fourth growing season (2005). <br />Kennacon Energy Co. / Colowyo Ilene Page 44 Revegeta0on Idonkoring -2003 <br />
